There are two ways that a substance ( called the System ) may release energy to the Surroundings :
( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.
( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.

What change releases energy into its surroundings?
An exothermic process releases energy into its surroundings.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
Contrast what happens to thermal energy in evaporation and condensation?
In evaporation, the heat is transferred to the substance being evaporated from some heat source or the surroundings. It is released by the substance.
The rate at which a substance conducts thermal energy is called?
substance mass
What system in which both energy and matter are exchanged with the surroundings is called a?
Closed system
What change releases energy into its surroundings?
An exothermic process releases energy into its surroundings.
What is a reaction that releases energy into its surroundings?
An exothermic reaction releases energy to its surroundings.
How does the energy of a substance change during an exothermic change?
During an exothermic change, such as freezing, the substance releases energy to its surroundings.
Chemical reaction that releases energy?
All chemical reactions that release energy in the form of heat are called exothermic reactions.
What name do you give to a substance to release energy?
A substance to release energy is usually called a fuel. A chemical reaction that releases energy is called exothermic.
A chemical reaction that releases energy is called?
Exothermic reactions
A process or reaction which releases heat to the surroundings is said to be?
Reactions that require energy in the form of heat are called endothermic.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What is a exothermic change?
It is when something releases its energy to its surroundings do to a system.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
What substance releases energy when it burns?
all
When a substance cools it loses what to its surroundings?
Thermal energy
